I have no idea how to start solving this problem. My professor gives really bad notes. I know you guys dont like to work problems without the asker doing some work, but i dont know where to start. If someone could walk me through this i would greatly appreciate it.

I dont know how to format matrices so i just copied the problem from the website. Each set of numbers in parentheses should be in a 1 column matrix (top, bottom).

Any help is greatly appreciated.

Consider the basis

of

consisting of vectors

(-2, 5) and

(-5, 4) .

Find

in

whose coordinate vector relative to the basis

is

(-1, 6) .
